Notes on plants of the southern United States — II 



Francis W. Pennell 



In the first series of these notes, pubHshed in the February- 

 Bulletin of this year, there was given a tentative revision of the 

 genus Cornmelina. The treatment of species there presented 

 difTered widely from current treatments and should probably 

 have been preceded by a fuller introductory statement. A sum- 

 mary of the conclusions reached may therefore be in place. 



Cornmelina communis L. is the common introduced weed of 

 the northeastern states. Both Cornmelina longicauUs Jacq. and 

 the little-known C. caroliniana Walt, have passed as C. nudiflora 

 L., but, as is shown on page 96, the latter specific name must 

 be retained for a plant of another genus, Aneilema ntidifloriim (L.) 

 Kunth. Strangely enough the Linnean Cornmelina nudiflora had 

 been perpetuated in the names of two species belonging to different 

 genera. Linnaeus's description of his Cornmelina virginica is 

 clear and diagnostic, and leaves no doubt that the plant he was 

 considering is that we have been calling C. hirtella Vahl. But the 

 plant which has been separated in recent floras, by reason of having 

 its capsule three-celled, as C. virginica, is but a state or condition 

 of C. erecta L. C. crispa Wooton and C. angustifolia Michx. are 

 continued as species but are very near, possibly not distinct from, 

 C. erecta. Cornmelina elegans HBK. is a widespread species of 

 tropical America. 



In the present paper further noteworthy records, based upon 

 my southern collections of 1912 and 191 3, are given, and revisions 

 are made of a portion of the genus Schoenocaulon, and of the Ne- 

 mexia subgenus of the genus Smilax. 



MISCELLANEOUS SPECIES 



Carex glaucescens Ell. 



This species was listed in the first series of these Notes (p. 95) 

 as C. verrucosa Muhl., a later name. See Mackenzie; Small, Fl. 

 SE. U. S. ed. 2, 1324. 1915.
